Left USB-C Ports Not Charging, But Work for Data Transfer
I have a Dell Precision 5550 laptop. Yesterday, I noticed that the charging connection on the left USB-C ports was disconnecting and reconnecting intermittently. Today, both left USB-C ports have completely stopped charging. However, they still work for data transfer and connecting USB devices. Currently, I'm using the right USB-C port for charging, but I'm worried it might also stop working.
Is there any known fix or solution for this issue?

There is a recent thunderbolt firmware update being released for your Precision 5550. Although it does not indicated any fix or enhancement for power delivery. It's up to you to decide to perform the firmware update.
